Also, I liked the running commentary between the various reporters. It almost felt like a sporting event.
- nitrogen 11y agoDoes anyone know if they analyze the wave patterns on the droneship and send that data to the rocket so it can tilt or time its landing to match? Or is it just the current tilt and position that's taken into account? Or is barge tilt even considered?
- matt-attack 11y agoI never understood all the fuss about the the movement of the barge until I saw this landing. Even after it landed I was nervous it would tip over given the apparent motion of the barge!
- ridgeguy 11y agoIt looks really dramatic, but it might not be close to tipping, really. I'd guess the fuel is very nearly depleted at landing. This would put the center of mass somewhere fairly low on the stage, close to the engines which are dense, heavy things. This means that the landed stage isn't as susceptible to toppling as it looks. At minimum, it would have to tilt so far that the CoM went beyond the line connecting the ends of two adjacent landing legs and tilt along a radius that crossed the midpoint of that line. Other tilt vectors would require more tilt to overturn the stage, based on CoM & landing leg geometry. Wind loads could assist a tipover. The stage is ~12 feet diameter, it's really tall, it presents lots of sail area and it's pretty light at landing. Wind force would be a fun estimation to do.
- Klathmon 11y agoI read somewhere that the droneship and rocket don't communicate at all. They both have their "plans" on what to do, and the rocket basically is doing everything from what it can "see". There is no back-and-forth communication happening at all.
- azernik 11y agoI think those are SpaceX PR people rather than reporters. The sports-event feel is clearly a consciously-constructed show.
- greglindahl 11y agoThe SpaceX people in the broadcast are mostly engineers and occasionally product managers. Listen to them introduce themselves.
